AL600UL3 / AL600UL3X Installation Guide - 3 -
Installation Instructions:
Wiring methods shall be in accordance with the National Electrical Code/NFPA 70/NFPA 72/ANSI, and with all
local codes and authorities having jurisdiction. Product is intended for indoor use only.
1. Mount unit in the desired location. Mark and predrill holes in the wall to line up with the top two keyholes
in the enclosure. Install two upper fasteners and screws in the wall with the screw heads protruding. Place
the enclosure’s upper keyholes over the two upper screws, level and secure. Mark the position of the lower
two holes. Remove the enclosure. Drill the lower holes and install the three fasteners. Place the enclosure’s
upper keyholes over the two upper screws. Install the two lower screws and make sure to tighten all screws
(Enclosure Dimensions, pgs. 7-8). Secure enclosure to earth ground.
It is recommended to first review the following tables for screw terminals, switch selection and LED status
indications. This will greatly facilitate installation hook-up.
Carefully review:
Stand-by Specifications (pg. 2)
LED Diagnostics (pg. 4)
Terminal Identification Table (pg. 4)
2. Connect AC power (115VAC 60Hz) to the terminals marked [L, N] (Fig. 1, pg. 5). Green “AC” LED on
power supply board will turn on. This light can be seen through the LED lens on the door of the enclosure.
Secure green wire lead to earth ground.
Use 18 AWG or larger for all power connections (Battery, DC output).
Use 22 AWG to 18 AWG for power-limited circuits (AC Fail/Low Battery reporting).
Keep power-limited wiring separate from non power-limited wiring (115VAC / 60Hz Input,
Battery Wires). Minimum 0.25” spacing must be provided.
For Fire Alarm applications the outputs are “Special Applications” only, see list (refer to Appendix A, pg. 6).
3. Measure output voltage before connecting devices. This helps avoiding potential damage.
4. Connect devices to be powered at 5VDC to the terminals marked [+ 5VDC –].
5. Connect devices to be powered at 12VDC to the terminals marked [+ 12VDC –].
6. Connect devices to be powered at 24VDC to the terminals marked [+ 24VDC –].
7. Connect two (2) 12V Stand-by batteries.
Note: For Access Control applications batteries are optional. When batteries are not used, a loss of AC will
result in the loss of output voltage. Batteries must be lead acid or gel type if used.
Use two (2) 12V stand-by batteries connected in series to the terminals marked [+ BAT –] (Fig. 1 , pg. 5).
8. It is required to connect supervisory trouble reporting devices to outputs marked [AC FAIL, LOW BAT]
(Fig. 1b, pg. 5).
Use 22 AWG to 18 AWG for AC Fail and Low Battery reporting. AC Failure will report in 5 minutes.
Note: When used in fire alarm, burglar alarm or access control applications, “AC Fail” relay should be
utilized to visually indicate that AC power is on. To delay report for 6 hours cut “AC Delay” jumper
(Fig. 1a, pg. 5).
9. Please ensure that the cover is secured with the provided key lock.
Wiring:
Use 14 AWG or larger for all power connections.
Note: Take care to keep power-limited circuits separate from non power-limited wiring (115VAC, Battery).
Maintenance:
Unit should be tested at least once a year for the proper operation as follows:
Output Voltage Test: Under normal load conditions, the DC output voltage should be checked for proper
voltage level (refer to Power Supply Voltage Output Specifications chart).
Battery Test: Under normal load conditions check that the battery is fully charged, check specified
voltage both at the battery terminal and at the board terminals marked [+ BAT –] to
ensure that there is no break in the battery connection wires.
Note: Maximum charging current under discharge is 0.7A.
Note: Expected battery life is 5 years, however it is recommended changing batteries
in 4 years or less if needed.
